Summary
The gates changed everything.
Jinwoo awakens in a dungeon and survives by sheer luck—rescued by an auburn-haired teen who disappears shortly after.
Then Jinwoo wakes up in someone else’s body.
Bound to Woo Jin-Chul by an unknown force, the two are pulled into a cycle of shared lives, shared battles, and shared sacrifices. As the world grows harsher and gates deadlier, one question remains:
How long can two people survive by trading places with death?

Given a second chance, Giyuu Tomioka walks a path he never imagined—one where every choice, every bond, could alter the future. By guiding Tanjiro, reconciling with Urokodaki, and seeking allies long before they were meant to be, he lays the first stones of a new tomorrow. It is both an ending and a beginning… the quiet start of a story yet to unfold.

Summary
After a brutal battle with a powerful demon, Giyuu Tomioka and Obanai Iguro are left stranded in the middle of a relentless blizzard — both gravely injured, far from the Demon Slayer Corps, and with no one aware of their location.
Giyuu has lost his sight, and Obanai can no longer stand. With only each other to rely on, they make an unspoken pact: Giyuu will walk, and Obanai will see.
Together, they begin the long, freezing journey home.

Summary
Kanroji brightens up at this immediately, her wide, toothy smile gladly making up for Shinobu’s contained one, sitting down on the tatami, bunching her fists and pumping them in the air, “What’s so exciting? Seeing you all happy like this gets me pumped up too!”
The pink-haired girl is practically vibrating, the dimple next to her lip obvious, heart shaped moles like little highlights on her pink cheeks. Shinobu chuckles guilessly, rolling up the letter again and placing it on the low table, shifting carefully in her seat.
“Well, It just so happens my brother will be coming home!” As the words brother spill from her lips, Shinobu finds she can’t hold back her smile anymore, her ever-present rage almost entirely null at the idea of Giyuu coming home. It’s been many years since she’s seen him in person, and it makes her naive with happiness and fear. She reaches up one delicate hand to cover her face, huffing in amusement when she hears Kanroji gasp.

Giyuu Kocho, twin brother of Kanae Kocho, finally comes home to reunite with his little sister.

Summary
The blue hedgehog smiled and leaned forward, extending a hand toward the smaller one. "Well, let's introduce ourselves! I’m Sonic."
Shadow barely paid attention to the name, but it settled in his mind regardless, repeating a few times in his thoughts. It suited him, somehow—fast, loud, and impossible to ignore.
The white hedgehog hesitated before finally speaking. "...Silver." His voice was quiet, raspy, as if he hadn’t used it in a while. But the moment Shadow heard it, the name clicked into place.
Both of them turned to look at him then, waiting. He frowned, hesitating for a moment before sighing deeply. "...Shadow."
Or—Shadow survives, finds a new home, and, without even noticing, becomes an older brother.
